What is Lisinopril (Zestril) used for?

How Lisinopril (Zestril) works

Lisinopril (Zestril) is an angiotensin-converting enzyme (ACE) inhibitor. It works by blocking a protein in your body called ACE from making angiotensin II, a hormone that normally squeezes your blood vessels.

By blocking ACE, lisinopril (Zestril) helps your blood vessels relax and open up. This lowers your blood pressure. It makes it easier for your heart to pump blood to the rest of your body and lowers stress on your heart.

Pharmacist tips for Lisinopril (Zestril)

pharmacist
  • You can take lisinopril (Zestril) with or without food at any time of day. It's most important to choose a time that works best for you and easy for you to remember. Take it around the same time each day to help you get consistent results.
  • If you're taking lisinopril (Zestril) for blood pressure, it's a good idea to check your blood pressure regularly at home. Write down your readings and bring them to your follow-up appointments. This can help you and your prescriber see how well the medication is working for you. They can see if you need any dose adjustments.
  • Dry cough can be a common side effect of lisinopril (Zestril). It often happens within the first few weeks or months of treatment, but it can also happen at any time. To help relieve this dry cough, try honey and a humidifier. But if it bothers you too much, tell your prescriber. They can help choose a different medication for you.
  • You might feel dizzy when you start taking lisinopril (Zestril) and when you switch to a higher dose. This can happen because the medication can lower your blood pressure. But it should get better over time as you continue to take the medication and as your body gets used to your new blood pressure. Stand up slowly and carefully to avoid falling. If you feel too faint, pass out, or fall, tell your prescriber.
  • Drink enough water to stay hydrated while taking lisinopril (Zestril). This is especially important on hot days or after exercising. Your blood pressure might drop too much if you get dehydrated. This can worsen dizziness and raise your risk of falls.
  • Tell your prescriber and pharmacist about all the medications you take or plan to take. Lisinopril (Zestril) can interact with other medications and can be harmful. For example, taking it with nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen (Advil) can cause kidney problems. Your care team can make sure your medications are safe to take together and make changes if needed.
  • Work with your care team or a dietician to create healthy meal plans that are low in salt. This can help lower your blood pressure and support your heart health.
  • Talk to your prescriber before using any salt substitutes that contain potassium. Lisinopril (Zestril) can raise your potassium levels. And salt substitutes with potassium can raise it even more. This can be dangerous.
  • If you're pregnant: Don't take lisinopril (Zestril) and talk to your prescriber. This medication can cause serious harm to an unborn baby. Your prescriber can help you choose a safer option. For high blood pressure during pregnancy, there are other safer medications options. They might also suggest lifestyle changes to help keep your heart healthy.

More tips for Qbrelis (lisinopril) 1 mg/mL liquid:

  • Only use an oral syringe or medication dose cup from the pharmacy to measure out your dose of Qbrelis (lisinopril). Never use household spoons because they aren't accurate, which can cause you to take the wrong dose. Ask the pharmacy for extra oral syringes or medication dose cups.
  • Store Qbrelis (lisinopril) at room temperature between 68ºF and 77ºF.

Risks and warnings for Lisinopril (Zestril)

Lisinopril (Zestril) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Harm to an unborn baby

Black Box Warning Don't take lisinopril (Zestril) while pregnant. This medication can seriously harm an unborn baby. It can cause problems with the baby's kidneys and other birth defects.

If you become pregnant while taking lisinopril (Zestril), stop the medication and tell your care team right away. Talk to your primary care provider or prescriber about a safer option for you. There are safer treatment options for high blood pressure during pregnancy.

Angioedema (swelling)

  • Risk factors: Black people | Having angioedema in the past

Although rare, people who take ACE inhibitors like lisinopril (Zestril) can have a serious reaction called angioedema. This involves swelling in different parts of the body, including the face, tongue, throat, and neck. Tongue or throat swelling can be life-threatening since it can make it hard to breathe.

Angioedema can happen at any time during treatment. The risk might be higher for Black people as well as older adults and people of female sex.

Get medical help right away if you have swelling of your face, mouth, tongue, throat, or neck. Also get help right away if you have trouble breathing, wheeze, or feel dizzy or faint. And call your care team right away if you have severe stomach pain (this can be a sign of swelling in the stomach). If angioedema happens, you'll have to stop taking lisinopril (Zestril).

Low blood pressure

  • Risk factors: Not enough fluid in your body (e.g., dehydration) | Having diarrhea or vomiting for a long time | Heart failure with low blood pressure | Other heart problems | Low oxygen to the heart or brain | Dialysis | Low sodium | Taking high doses of a diuretic

Sometimes, lisinopril (Zestril) can make your blood pressure drop too much. Low blood pressure can make you feel dizzy, tired, or lightheaded. This side effect is more common when you first start the medication and when the dose is raised.

If your blood pressure drops too much and you feel dizzy, sit down slowly until you feel better. Hold onto something sturdy when you stand back up to help keep your balance. If you often feel dizzy, lightheaded, faint, tired, or confused often while taking lisinopril (Zestril), tell your prescriber. And if you fall and hit your head, get medical help right away.

Possible worsening of kidney problems

  • Risk factors: Severe heart failure | Kidney problems | Not enough fluid in your body | Taking other medications that can cause kidney damage | History of narrow heart valves (aortic stenosis)

Lisinopril (Zestril) can help protect the kidneys for some people. But in some cases, it can make kidney problems worse. This risk might be higher if you already have kidney problems, have severe heart failure, or had a heart attack.

Your prescriber might order lab tests while you take lisinopril (Zestril). This helps them check that your kidneys are healthy and working properly. Also tell your care team about all the medications you take so they can check for any that can worsen kidney function.

Watch for signs that your kidneys might not be working well, like urinating less than usual. If this happens, tell your care team so they can see what's going on.

High potassium levels

  • Risk factors: Diabetes | Kidney problems | Taking other medications that also raise potassium | Taking potassium supplements | Using salt substitutes that contain potassium

Lisinopril (Zestril) can raise your potassium levels, which can be dangerous. The risk is greater if you have diabetes or kidney problems. The risk is also higher if you take other medications or supplements that raise potassium. Make sure your care team knows your full medical history and all the medications you take.

Symptoms of high potassium include tiredness, nausea, muscle weakness, or numbness or tingling. It might also cause an irregular heartbeat. Tell your care team right away if you notice these symptoms while taking lisinopril (Zestril).

Liver problems

It's rare, but ACE inhibitors like lisinopril (Zestril) might be linked to the development of a blocked bile duct. This can lead to liver problems and sometimes even liver failure. Your prescriber might order blood tests to check your liver health from time to time.

Watch for symptoms of liver problems while taking lisinopril (Zestril). This can include tiredness, stomach pain, or yellowing of your skin or eyes. If this happens, let your care team know right away so they can check out what's going on.
